I'm using Daemon Tools Lite to play a game I have copied on the computer in .iso format. I'm able to use Daemon's virtual drive to install the game, but when i go to play the game it just opens a picture of a bridge, as if it were about to start the game but just stops there. I've done it before but that was years ago, with a friends help from another friend. Is this were I use the emulators. what exactly are these for.

Use the original, put it into the drive and run SETUP.

If you created an .ISO,it won't work,because the image has no information stored about the used copyprotection.
99.9% of today's games are protected,and they need a more advanced imageformat to create a succesful backup.

Daemon-Tools Pro and/or Alcohol 120% are my recommendations to get a high succes rate.

I no longer have the original it was damaged.

Not the best solution to throw it away......
perhaps there is a possability to get it working,but you can't ask it here.........google is your friend.....

I've found a forum about copy protection could this be my problem. I remember when I was doing this with a friend we had to do something to a file after installing it i believe, man it was like 5-6 years ago so its hard to remember.
